zypper parallel downloading of packages

Feature state

openSUSE Distribution
Rejected Information


Now, i think that this is already done with apt.

What should happen is that zypper should download packages

concurrently and when it does download them all, then it should install them

User benefit:

Faster package management

IMHO the default setting for zypper should be (1) download and ONLY after download of all selected apps/dependencies is complete then (2) install.

This feature and comment #1 does not contradict #120340 (parallel download and install). First, even if we download and install in parallel, we still can download multiple files at once. Second, download-all-install-all can still be the default, while alternating download-few-while-installing-one, can be enabled on request or in zypp(er).config (like it is now with download-one-install-one).

Does Zypper still suffers from this?

We still don't download multiple files in parallel.

But the MultiCurl backend (replacing ARIA as default since libzypp-8.0.1) implements MetaLink and Zsync support. So we download multiple portions of the same file in parallel from multiple mirror locations, if the hosting server supports it.

So my question now is: would there be any gain of speed to also add a "parallel downloading of packages", or there's not point in doing that since we already "download multiple portions of the same file in parallel"?

I don't know if someone measured it, but I don't expect a big gain when downloading from a server supporting MetaLink/Zsync.

Of course if the hosting server does not support it, the gain would be significant.

Ok, so this means it still is a good idea to implement this feature in order to obtain more speed. :)

Yum in Fedora is now doing parallel downloads, and what it appears to manage to do is keep a limited bandwidth link (I'm talking 6Mps DSL here) nice and full, as there's no pause between individual downloads as a new connection to the download server, as there are typically a number of different RPMs actively downloading at any time.

openSUSE 13.2 is out, is there still interest for this feature ?

In my case I'm using openSUSE Factory as rolling release and as you might know the number of updated packages is usually quite high. Having parallel download would help speed this up. :-)
